Design

The vessel was the first of four ships designed by Conoship International[5] and D.W. den Herder maritiem, with a shallow draught and high manoeuvrability for difficult port construction, maintenance, land reclamation, coastal defense and offshore energy projects.[6] The typical carpentry needed for a vessel of this kind was completed by Hans Dorgelo. It was the first dredger in the Boskalis fleet to use azimuth thrusters as its main means of propulsion. The ship is equipped with rainbow discharge valves for beach replenishment[7] or land reclamation, two jet water engines for sediment dispersal, non-protruding bottom doors in the hopper (cargo hold) for dumping at sea and engines designed to stringent MARPOL sulphur emissions standards.

Capabilities

Equipped with a suction pipe with a diameter of 900 mm (2 ft 11 in), a dredge pump of 1,680 kW (2,250 hp), two jet pumps of 746 kW (1,000 hp) and a maximum dredging depth of 30 m (98 ft 5 in) the ship is able to pump its load ashore by pipeline, dumping or rainbowing.

Sister Vessels

Its sister vessels of the Shoalway class include the Causeway, the Strandway and the Freeway.
